Posts referring to the LG Electronics PB61U

Found this video the other day and thought it was pretty interesting, shows the LG PB63U alongside a competitor's unit, which is rated at less lumens than the LG. Somehow, the competitor was much brighter in the video, and colors were insanely better reproduced.
The videos they played in the video are the same, but there is a huge difference in them in terms of what is actually being displayed.
Any reason why LG would do this? They're a huge brand, how can they get away with this?
